Synthesis and properties of a triarylamine derivative with a coordination site and its copper (II) complex

A ligand, 4-(bis(2-picolyl)aminomethyl)-4′,4″-dimethyltriphenylamine ((2-py)2TPA) and its copper complex were designed and prepared in order to examine intramolecular interactions of organic cation radical–metal ion. CV measurements of the copper complex showed reversible CuI/CuII and TPA/TPA+· redox couples. The spin–spin interaction in [Cu((2-py)2TPA)Cl]2+ generated upon one electron oxidation of the copper complex was examined by ESR measurements.

A novel ligand with a redox active triarylsamine unit and its copper complex were designed and synthesized. Electrochemical and spectroscopic properties of the complex were examined.Figure optionsDownload as PowerPoint slide
